Top jewellery myths: What you need to know

19th November 2025

Ever wondered if biting gold proves it’s real or if mixing metals is a fashion faux pas? Jewellery has long been surrounded by stories, traditions and half-truths that shape how we buy and wear it. From so-called ‘rules’ about which metals suit your skin tone to old wives’ tales about cleaning gemstones, these jewellery myths can often lead to confusion – or even damage your favourite pieces.

In this guide, we’re uncovering the truth behind the most common jewellery myths. Whether you’re investing in gold, shopping for an engagement ring or simply looking to care for your jewellery properly, we’ll help you separate fact from fiction.

Myth 1: Diamonds are the most expensive gemstones

Diamonds have long been marketed as the ultimate symbol of luxury, but their reputation doesn’t always reflect reality. While they’re prized for their brilliance and meaningful significance, they aren’t necessarily the rarest or most valuable gemstones. Stones like alexandrite, red beryl and painite are far less common and generally more expensive. Typically, gemstone value depends on individuality, quality and demand. So, while diamonds are one of the most popular stones, this gemstone myth reminds us that rarity is what determines true worth.


Myth 2: Diamond is the best stone for an engagement ring

One of the most enduring diamond myths is that a diamond is the only ‘proper’ choice for an engagement ring. In reality, the best gemstone is one that fits your lifestyle, budget and taste. Sapphires, moissanite and emeralds are all stunning, durable alternatives that offer unique colours and symbolism. While diamonds remain the most traditional option, this engagement ring myth overlooks individuality and personal preference. Ultimately, you should pick a stone that feels meaningful to you and your partner. Interested in a gemstone engagement ring? Check out our top picks for 2025.

Myth 3: All gold is the same

When it comes to gold myths, one of the biggest misconceptions is that all gold jewellery is created equal. In reality, gold differs in purity, durability and value. Pure 24-carat gold is soft and prone to scratches and bending, while lower-carat gold, such as 14-carat or 18-carat, is alloyed with metals like silver or copper for added strength, making it ideal for everyday wear. In our gold guide, you can learn more about the purity of each carat and what alloys are used to create a specific type of gold.

Another common myth? That ‘biting gold’ can prove authenticity by seeing if teeth marks are left. This outdated trick can actually damage both your jewellery and your teeth. It’s also crucial to distinguish between solid gold, gold-plated and gold-filled jewellery. Understanding these distinctions helps ensure you’re making informed purchases and getting fair value for your jewellery.


Myth 4: You can’t wear gold & silver together

Forget the old metal mixing myths – today, combining gold and silver is a trend that’s widely embraced. Modern style champions versatility and mixing metals can add depth and character to your look. To achieve balance, try distributing metals evenly and use transitional pieces that will help to blend the different tones. For instance, pair a gold pendant with a silver chain or stack mixed-metal rings.

Myth 5: Your skin tone can only wear one metal colour

This metal myth suggests that warm skin tones can only wear gold and cool tones should stick to silver, but this isn’t always the case. While certain metals may complement undertones differently, personal preference should always win. If you love rose gold, platinum or a mix of metals, wear what speaks to your style.

Myth 6: Jewellery can be cleaned with toothpaste

One of the most persistent jewellery cleaning myths is that toothpaste is a safe, effective cleaner. In reality, it’s abrasive and can scratch metals and dull gemstones. Instead, opt for mild soap, warm water and a soft cloth or take your jewellery for a professional clean. Understanding proper care techniques ensures your pieces last beautifully for years to come.

Myth 7: Wearing silver causes skin discolouration

Another common misconception is that silver jewellery can discolour the skin. While some people may notice a faint greenish tint after wearing silver, it’s not a sign of poor quality. Silver alloys can react with natural elements on your skin – such as sweat, lotions or even humidity – resulting in temporary tarnish. It’s also worth noting that sterling silver (92.5% pure silver) is generally more resistant, while plated silver may show wear more quickly. To help prevent discolouration, keep your jewellery clean and dry.

Myth 8: Bigger diamonds are better

It’s not necessarily the bigger the better when it comes to diamonds. A large stone with poor cut or clarity may sparkle less than a smaller, well-cut gem with exceptional brilliance. The true measure of a diamond’s beauty lies in the 4Cs: cut, colour, clarity and carat weight. So, this diamond myth actually overlooks what truly matters: quality and craftsmanship. Our advice? Always go for sparkle over size.
